Heavy rain and landslides over southern KeralaDate: 19 October 2021 Tags: Disaster & Disaster Management
Heavy rains have caused floods and landslides in the central and southern districts of Kerala.
The incident follows fury of 2019 when large-scale infrastructure was damaged due to heavy rains and resulting effects.
Large number of bridges and roads have washed away owing to flash floods. The Kottayam district has been the worst hit.
A low pressure system in east-central Arabian Sea is said to be the main reason for such intense rains. This system moved closer to Kerala coast to cause the damage.
Atleast six of the southern districts of the state have obtained extremely heavy rain in the past few days.
Districts such as Thrissur, Idukki, Alappuzha, Kottayam, Ernakulam, Pathanamthitta, Kollam and Thiruvananthapuram witnessed flash floods, mudslides and landslides.
Monsoon has withdrawn from most part of India. However, it is still active in Southern peninsula. States such as Kerala has been witnessing thunderstorms due to this phenomenon.
Rainfall during October is common in Kerala due to North-east monsoon. But the present weather system is isolated and not connected to North-east monsoon.
It is a meteorological phenomenon that brings rainfall to certain parts of southern peninsular India.
The north-east monsoon is important for states such as Tamil Nadu and southern Andhra Pradesh as it contributes majorly to annual rainfall.
Tamil Nadu lies parallel to Bay of Bengal branch of South-west monsoon and does not receive rainfall. The North-east monsoon compensates the shortage.
